Chapter some basic principal and techniques in organic chemistry and we are doing the topic Heterolytic Fission in covaland bond.Hello Friends the last lecture being studied about the Heterolytic Fission of hemolysis and now are going the topic which is based on the Heterolytic Fission so what is Heterolytic Fission and we’ll take a example of this to make you understand that what is actually Heterolytic Fission which is not we could call it Heterolytic Fission what is that let’s talk about so talking about the heterotic vision we should understand the definition of it so let us understand it very clearly that is the unsymmetrical breaking of a covalent bond between the two atoms such that the more electronegative atom acquires both the electrons of the shared pair is called as Heterolytic Fission so let me give you an example and because of which we could easily get understand that is what is actually Heterolytic Fission so talking about the first one that is suppose this is a direction that we have and or for which we have to do a fusion on it and suppose in among the atom A and B the B is the one which is more electronegative so obviously we know that during a covalent bond to deform the bonds are where the electrons are being shared equally and that’s the reason that the bond is formed because of the shared pair of electrons and but meanwhile suppose if one of it is the more negative value the other one is more electro positive then we would get to know that the shared pair of electrons will be transferred or the both electrons will be transferred to the one which is smooth and negative after two the fusion and then it’s a reason that I suppose it B is more electronegative then we could find that and that is the representation we should do this kind of representation has to represent that the electron has been transferred from A to B suppose in this case that this happened and what we could see you could see that the products that have been formed is basically the a which has lost its electron BCD it cannon has been formed Karen has been formed because the one which has a positive charge are known as Catan and when the B which has it’s only a tone but meanwhile because it is more electronegative it will acquire the electron of the other end of that is from which it was been associated so now it will now acquire the electron of itself along with that of the electron of a so that is the reason it will acquire a negative charge making this to be called as cation and this what we call as and then so this is the efficient that takes place but yes what is the main criteria for a reactant to undergo catalytic fusion or to show heterolytic that is heterosis the reason is busy obviously in the Atomic Kitten item that is present in the molecule and this is how we get the cation and NN during the bond future and the more important thing is we have to use a particular solvent because in it is very easy to understand that when we have did homolytic we have introduced a particular non porous or an end because of that only we could see that the free radicals would be dissociated or or the free radicals reform because the dissociation of or the bond breaking of the reactants and that is the reason that for that we need a non-polar solvent because we don’t need the reaction between the nonpolar solvent and that of the radical but meanwhile if we are talking about the hydrolytic fusion so in this case the ionic products have been formed that is a cation and NN so that is the reason that we are using basically polar solvents so the pore installment is very much necessary so as to make the environment for the products or for the for the species that has been generated of the ready hetero diffusion so as to maintain a stability and so as to give a kind of approach that mean we so as you know one more see that like dissolves like and that’s the reason that we could say that term for using a non-polar solvent so that is the reason that we could get a homolytic feature with that case while choosing a polar solvent we could get a catalytic fusion so let me introduce another example so as to clarify it suppose so this is ch3cl and in the for which it is undergoing in the hetero diffusion so obviously we know that the chlorine atom is basically more electronegative compared to that of the methyl one and moreover you know that methyl 1 is the one which with the she has basically a plus I effect at rest it will donate the rate or no or it will push the its electron towards the other atom which is more rate or negative so that’s the reason that we could also symbolize by this arrow and we could see that the hetero diffusion will occur in such a way that the electron of the CHC that is the in turn of the carbon if I would say more precisely that would be shifted towards the Chloe so as to form basically CH 3 plus or B cereus carbo cation and meanwhile we could get CL minus so this is what we have got a contend and I’m so the only resultant thing that we have got is because of the user of basically polar solvent so the environment that should be maintained for in this case should be porous for me so therefore this is the two difference that we would get over here and okay about the next thing in this case the methyl cation has been formed while I’m talking about the one which has took place suppose if we have did a home attic fusion for Ethan and in that case we also have got a methyl but that one was withheld radical and that methyl radical is very short living species while that of the this methyl cation that could be stabilized by the other environment that are present in it around it so that is the reason this is the other two difference that I have also mentioned over here as well as we have also mainly discuss about the heterolytic fusion that’s it I want to explain and thank you for watching this video I hope you have liked this video and I hope you’ll share this with friends and s don’t forget to subscribe occasion thank
